Radial Leaded > 600R Series

The 600R Series is designed to protect against power fault

events typically found in telecom applications. This series is

designed to be used in applications that need to meet the

requirements of GR–1089-CORE and UL60950/EN60950/

IEC60950. These resettable devices also help to meet the

requirements of ITU K.20, K.21 and K.44.

Caution: Operation beyond the specified rating may result in damage and possible arcing

and flame.

*

* Effective February 11, 2010 onward, all 600R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 600R PTC products may continue to be sold, until

supplies are depleted. This change will have no effect on 600R product specifications or performance.

600R Series

WARNING

• Users shall independently assess the suitability of these devices for each of their applications

• Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or fire

• These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such

conditions are expected to be repetitive or prolonged in duration

• Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices

• These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses

• Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device.
